MEANS FOR CONVEYING HEATING 0R MOTIVE AGENTS THROUGH A TRAIN OF CARS.

SPECIFICATION forming part of Letters Patent N o. 263,264, dated August 22, 1882. Application tiled May 20, 1882. (No model.)

To all whom it may concern:

Be it known that I, MAURICE J. WALSH, of New York, in the county and State of New York, have invented a certain new and useful Improvement in Apparatus for Conveying a Heating or a Motive Agent along a Train of Gars or from a Locomotive to a Oar, of which the following is a specification. v

The object of my improvement is to afford 1o provision for connecting pipes employed to convey a heating or a motive agent from a locomotive or other source of supply to a car or cars in suoli manner as to allow of a yielding motion of the portions of pipes which extend between the locomotive and car or between cars.

lVhile I intend this improvement especially for application to pipes for conveying a heating agent through a train of cars, it is appli- 2o cable to a pipe for conveying a motive agent along a train of cars for operating a brake.

The improvement consists in the combination, with a pipe for conveying a heating or motive agent along a car, of a section of rigid pipe for extending beyond the car, and connected to the pipe which extends along the car, so as to be adapted to move vertically and laterally relatively thereto, and another section of pipe telescopically fitted to the section 3o rst named, and having secured toits outer end a coupling-piece. If two pipes are extended through a carto convey a heating agent back and forth through the same, duplicate telescopic sections of the kind mentioned will 3 5 preferably be provided beyond the car, so as to be independently accessible. Acock may with advantage be employed to control communication between the fixed pipe and the telescopic sections, where they are employed for a heat- 4o ing apparatus, so as to return the heating agent from the outer to the inner pipe at the rear end of the last car of a train.

In the accompanying drawings, Figure l is a longitudinal section of a combination of pipes embodying my invention for a heating apparatus, and Fig. 2 is a plan of certain parts of the same.

Similar letters ot' reference designate corresponding parts in both figures.

5o A designates a pipe designed to be affixed to the floor of a car for conveying steam or other heating agent through the same, and B designates a pipe arranged within the pipe A for conveying the heating agent back again. These pipes have secured to their ends the barrel0t'acock,C,which preferably, for reasons which will be evident hereinafter, will be externally of spherical form. The plug of the cock may be of the usual conical form.

Applied to the exterior of the barrel of the 6o cock is a shell,D, which is formed in two parts, which are secured together by screws s or other suitable means, and is adapted to form, with the barrel of the cock, a ball-and-socket 'oint. l J To the shell l) are secured sections of rigid pipe A' B', communicating with separate passages a b, leading to chambers a b in the barrel of the cock.

Fitted to the exterior ot the sections of pipe 7o A B are sections of rigid pipe A2 B2. The sectionsAA2 and B B2 arepacked atthe ends to form a tight joint. At the outer ends the sections of' pipe A2 B2 are connected to a coupling-piece, E, of any suitable kind, whereby they may be united to a corresponding coupling-piece secured to similar sections ot' rigid pipe.

It will be obvious that the sections of pipe A2 B2 may move relatively to the sections of 8o pipe A B', and that all these sections ot' pipe may move together upward or laterally to accommodate themselves to the motion of the carto which they are attached relatively to an adjacent car.

The plug of the cock has ports c d, the former of which, when the plug is properly turned, will establish communication between the chambers a b in the barrel ot' the cock and chambers a2 b2 inV said barrel, which communicate 9o with the pipes A B,and that thus the pipes A B and the sections of the pipe A B will be put in communication. The plug of the cock has also a port, e, consisting of a cavity or recessl in its exterior, which, when the plug is turned into a different position, will establish communication between the chambersa2 b2 to put the pipes A B into communication to cause the heating agent to pass from one to the other.

It" the improvement be used for conveyrco ng a motive agent to operate a brake, the giipe B, the rigid sections B B2, the chambers "1 b2, and the ports d and e may be omitted.

The barrel ot' the cock may be made cylinllric, and the up-and-down motion may be provided for by another joint on a transverselyextendiinglr pipe, if desirable.

What- Iclaim as my invention, and desire to secure by Letters Patent, is-

1. The combination, with a pipe for conveying a heating or motive agent along a car, of a section of rigid pipe for extending beyond the car, and connected to the pipe which eX- lends lalong the car, so as tobe adapted to move vertically and laterally relatively thereto, and x 5 another section of pipe telescopically fitted to the section first named, and having secured to its outer end a coupling-piece, substantially as specified.

2. The combination of the pipes A B, the 2o telescopic sections A A2 B B2, the cock C, having au externally spherical barrel, and the shell D, substantially as specified.
